Red Lion ZPJ - FLEXIBLE ARM MOUNT - Manual

MODELS ZPJ - LARGE THRU-BORE ROTARY PULSE GENERATOR
GENERAL DESCRIPTION
The Model ZPJ ia a thru-bore encoder with a bore of 0.625" (15.875 mm).
Additional mounting kits are available to adapt it to both standard and metric
shaft sizes. This unit is ideal for applications requiring a miniature, high
precision, low cost encoder, designed with all metal construction for years of
trouble-free operation.
The ZPJ encoder has a flexible arm mount and blind hollow shaft. It uses two
set screws that are 90° apart to clamp the encoder's hub to the motor shaft. The
NPN Open Collector outputs are each current limited to 20 mA. The outputs are
standard quadrature with index, and are available in resolutions up to 2500
pulses per shaft revolution. The quadrature separation is typically 90 electrical
degrees. Output A leads output B for clockwise rotation of the encoder shaft.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
literature or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Open Collector Output Wiring
The ZPJ encoder has open collector outputs. An open collector output brings
the uncommitted collector of the encoder switching device to the external
world. Because the collector element is not associated with the sensor supply
voltage, the sensor output collector may be “pulled up” to external voltages
different than the encoder supply voltage (30 VDC maximum). NPN open
collector outputs are current sinking devices. An output signal will not be
generated unless a pull-up resistor is connected from the open-collector to the
positive side of an external supply. The same supply can be used for powering
the unit and for the pull-up resistor.
